ABSTRACT:
Equipment to erase the mesh pattern caused by the arrangement of the optical fibers in an endoscope which uses the optical fiber bundle as an image transferring means. This equipment erases the mesh pattern without decreasing the resolution by providing optical low pass filters to cut off the spatial frequency component higher than the resolution which is specified by the arrangement of the optical fibers on both sides of the image transferring means.
